Answer:
-2, 6, 20 ,...
Step-by-step explanation:
3n² +5n -2
if n=0 , then 3*0² +5*0 -2= -2
if n=1, then 3*1² +5*1 -2 = 3+5-2 = 6
if nu 2, then 3*2² +5*2 -2 = 12 +10 -2 = 20
Answer:
3.6*10^3
Step-by-step explanation:
What is the quotient of 2.592× 10^7÷7.2×10^4
2.592× 10^7÷7.2×10^4
= (2.592/7.2)×10(7-4)
= 0.36*10^3
= 3.6*10^-1*10^4
= 3.6*10^(-1+4)
= 3.6*10^3
Hence the quotient expressed in scientific notation is 3.6*10^3
